made; or, in lieu of prohibiting the transfer of stock, may fix a day and
hour not more than fifty (50) days prior to the day and hour then fixed for
the holding of any meeting of stockholders or prior to the last day on which






As amended through May 7, 1993.        8





the consent or dissent of stockholders may be effectively expressed for any
purpose without a meeting as the time as of which stockholders entitled to
notice of and to vote at such meeting or whose consent or dissent is required
or may be expressed for any purpose, as the case may be, shall be determined,
and all persons who were holders of record of voting stock at such time and
no others shall be entitled to notice of and to vote at such meeting or to
express their consent or dissent, as the case may be.  The Board may fix a
day and hour not exceeding fifty (50) days preceding the date fixed for the
payment of any dividend or the making of any distribution, or for the
delivery of evidences of rights or evidences of interest arising out of any
change, conversion or exchange of capital stock, as a record time for the
determination of the stockholders entitled to receive any such dividend,
distribution, rights or interests, and in such case only stockholders of
record at the time so fixed shall be entitled to receive such dividend,
distribution, rights or interests.  The Board at its option, in lieu of so
fixing a record time, may prescribe a period not exceeding fifty (50) days
prior to the date fixed for the payment of such dividend, distribution or
delivery during which no transfer of stock on the books of the Corporation
may be made.

     SECTION 4.  Lost, Destroyed or Mutilated Certificates.  In case of loss,
destruction or mutilation of any certificate of stock, another may be issued
in its place upon proof of such loss, destruction or mutilation and upon the
giving of a bond of indemnity to the Corporation in such form and in such sum
as the Board may prescribe; provided, however, that a new certificate may be
issued without requiring any bond when, in the judgment of the Board, it is
proper to do so.

     SECTION 2.  Books.  There shall be kept at the principal office of the
Corporation correct books of account of all the business and transactions of

office of the transfer agent of the Corporation, the stock book of the
Corporation, which shall contain the names, alphabetically arranged, of all
persons who are stockholders of the Corporation, showing their respective

in person, or, in the case of a stockholder, by his duly authorized attorney,
waive such notice in writing (which shall include the use of telegraph,
cable, radio or wireless), whether before or after the meeting or other
matter or event in respect of which such notice is to be given.

                                ARTICLE XI

                                FISCAL YEAR

     SECTION 1.  The fiscal year of the Corporation shall end on the 31st day
of December in each year.

                                ARTICLE XII
                                     
                              INDEMNIFICATION

     SECTION 1.  Right of Indemnification.  Each person who was or is made a
party or is threatened to be made a party to or is involved in any action,
suit or proceeding, whether civil, criminal, administrative or investigative
("proceeding"), by reason of the fact that he or she or a person for whom he
or she is the legal representative is or was a director or officer, employee
or agent of the Corporation or is or was serving at the request of the
Corporation as a director or officer, employee or agent of another
corporation including subsidiaries of the Corporation, or of a partnership,
joint venture, trust or other enterprise, including service with respect to
employee benefit plans, whether the basis of such proceeding is alleged
action in an official capacity as a director, officer, employee or agent or
in any other capacity while serving as so requested as a director, officer,
employee or agent, shall be indemnified and held harmless by the Corporation
to the fullest extent permitted by the New York Business Corporation Law, as
the same exists or may hereafter be amended (but, in the case of any such
amendment, only to the extent such amendment permits the Corporation to
provide broader indemnification rights then said law permitted the
Corporation to provide prior to such amendment) against all expenses,
liability and loss (including attorneys' fees, judgment, fines, ERISA excise
taxes or penalties and amounts paid or to be paid in settlement) reasonably
incurred or suffered by such person in connection therewith.  Such right
shall be a contract right and shall include the right to be paid by the
Corporation expenses incurred in defending any such proceeding in advance of
its final disposition; provided, however, that the payment of such expenses
incurred by a director or officer of the Corporation in his or her capacity
as a director or officer (and not in any other capacity in which service was
or is rendered by such person while a director or officer, including, without
limitation, service to an employee benefit plan) in advance of the final
disposition of such proceeding, shall be made only upon delivery to the
Corporation of an undertaking, by or on behalf of such director or officer,
to repay all amounts so advanced if it should be determined ultimately that
such director or officer is not entitled to be indemnified under this section
or otherwise.

     SECTION 2. Right of Claimant to Bring Suit.  If a claim under Section 1
is not paid in full by the Corporation within 90 days after a written claim
has been received by the Corporation, the claimant may at any time thereafter
bring suit against the Corporation to recover the unpaid amount of the claim,
and if successful in whole or in part, the claimant shall be entitled to be
paid also the expense of prosecuting such claim.  It shall be a defense to
any such action (other than an action brought to enforce a claim for expenses
incurred in defending any proceeding in advance of its final disposition
where the required undertaking has been tendered to the Corporation) that the
claimant has not met the standards of conduct which make it permissible under
the New York Business Corporation Law for the Corporation to indemnify the
claimant for the amount claimed, but the burden of proving such defense shall
be on the Corporation.  The failure of the Corporation (including its Board
of Directors, independent legal counsel, or its stockholders) to have made a
determination prior to the commencement of such action that indemnification
of the claimant is proper in the circumstances because he or she has met the
applicable standard of conduct set forth in the New York Business Corporation
Law, shall not be a defense to the action nor shall an actual determination
by the Corporation (including its Board of Directors, independent legal
counsel, or its stockholders) that the claimant had not met such applicable
standard of conduct, create a presumption that claimant had not met the
applicable standard of conduct.





As amended through May 7, 1993.        10





     
     SECTION 3.  Non-Exclusivity of Rights.  The rights conferred by Sections
1 and 2 shall not be exclusive of any other right which such person may have
or hereafter acquire under any statute, provision of the Articles of
Incorporation, By-laws, agreement, vote of stockholders or disinterested
directors or otherwise.

     SECTION 4.  Insurance.  The Corporation may maintain insurance, at its
expense, to protect itself and any such director, officer, employee or agent
of the Corporation or another corporation, partnership, joint venture, trust
or other enterprise against any such expense, liability or loss, whether or
not the Corporation would have the power to indemnify such person against
such expense, liability or loss under the New York Business Corporation Law.

                                AMENDMENTS

     SECTION 1.  These By-laws or any of them may be altered, amended or
repealed, or new By-laws may be adopted, by the vote of a majority of the
whole Board at any regular or special meeting thereof, or by the vote of the
holders of a majority in number of the issued and outstanding shares of stock
of the Corporation given at any annual or special meeting of stockholders,
provided that notice thereof shall have been given in the notice of such
meeting of stockholders.  The power of the Board to make, alter, amend and
rescind the By-laws of the Corporation shall be subject to such restrictions
and regulations, if any, as may be contained in any By-laws made and adopted
at any time by the stockholders.  Any By-law adopted, amended and repealed by
the Board which regulates an impending election of directors shall be set
forth in the notice of the next meeting of stockholders for the election of
directors, together with a concise statement of the changes made.
